Yes, you do. There is enough human history to know that government expands as much as possible and abuses any powers given. That's why the founders didn't allow for a national sales tax or a national income tax.
I think a lot of freepers would like to see either a flat tax or national sales tax implemented with the elimination of the income tax.
Some of us want to see the 16th amendment repealed and the income tax replaced with nothing. Return to having the government doing what was given to it to do in article 1, secion 8 of the US constitution and they don't need much money at all. What they need they can get off constitutional funds sources.
